Question

C++ Language

1. Match the description / meaning with the C++ syntax.

-       A.       B.       C.       D.       E.    external class or method that can access private members       -       A.       B.       C.       D.       E.    scope resolution operator       -       A.       B.       C.       D.       E.    extends       -       A.       B.       C.       D.       E.    dot operator       -       A.       B.       C.       D.       E.    modulus

A. :: B. : C. . D. friend E. %

2. Why would you prefer to use recursion?(answers can be one or more than one)

a		When the problem to be solved is naturally recursive, a recursive algorithm provides a clear and simple solution.
b		Since stack memory is faster than heap memory, and recursion uses stack memory, it is preferable to use recursion.
c		If a language, like LISP, or a subset of a language, like C++ templates, provides recursion but does not provide looping, then use recursion.
d		Since recursive functions call themselves, they avoid redundant code, and generate LESS code than functions that use looping.

Answer 1

`Hey,

Note: If you have any queries related to the answer please do comment. I would be very happy to resolve all your queries.

1) external class or method that can access private members

-friend

2) scope resolution operator

::

3) extends

:

4) dot operator

.

5) modulus

%

2) OPTION A AND B IS CORRECT

Kindly revert for any queries

Thanks.
